@Myk - I've tried all vg, all pg and 50/50. Have tried several vendors - janty, ovale, gh1, dekang, dulice etc - It all gives me the same buzz and the stronger the nic, the heavier the buzz. It's an awesome buzz too, really refreshing and stimulating ha ha! Not so good for evening time though, so I vape at 6mg now, which still gives me a great nic buzz (similar to a GOOD dbl espresso buzz but better, honestly) but doesn't give me insomnia. I have a very sensitive nervous system. As to your question - my favorite is 100% PG, no sweet undertaste, and way easier on atty life. I can vape 100ph on an ego c atty all day and not get one bad hit.
This I like, good old fashioned common sense. You know what? Tonight I'm going out to the local pool comp with my best friend and am going to just drink cokes and really get vape happy with my favorite RY5 and focus on that buzz instead of drinking.
Anyway I had two stinkies last night and now it's morning here in smoggy Shanghai and I'm vaping Super Strong Mint 100%pg with my coffee and it's awesome because the mint or menthol are my ADV and it's really making my lungs, mouth and head feel all fresh, minty and cleaned out lol. And as I mentioned it gives me a really stimulating feeling, so I'm all good about last night.
Yeah tonight I'll experiment and see what it's like alternating the beer for the vape train instead, swap one pleasure for another, I think I'll be fine with that and it's better (and cheaper) for me anyway.
Then when I do have my next couple of pints, I'll probably just have one or two analogues if I really fancy them and then get over it. Like others mentioned - it's the bigger numbers of non smoked ones that really matter. I don't see myself getting overly technical and doing the WTA thing etc, it's too much like trying to get back to smoking as close as you can without smoking, kind of a fool's errand perhaps as I don't think of vaping as smoking at all, it doesn't taste, or feel like it at all when sober, it's much cleaner, fresher and enjoyable.
IN ALL HONESTY if the pack wasn't in my apartment last night, I'd not have bothered anyway, so they go out with the trash this morning. If they're not there next time i get home after a cpl of pints and I get a craving, I'll just think 'I don't have any and don't do that any more, so get over it' and then have a shower and go to bed anyway.
My friend is going to find it weird seeing me drink only cola or non alc cocktails tonight, but he'll just have to get over it lol as i want to see what it's like.

Very interesting.
